You can sel ect the approp ria te test by pattern. Also, you can enter multiple selections by
separating them with commas.
To verify HP XC licensing, enter a command in the following format:
# ovp -v=license
By default, if any part of the verification fails, the ovp command ignores the test failure and
continues with the next test. You can use the --failure_action option to control how the
ovp command treats test failures.
The ovp command stores a record of the verifi cation in a log file in the
/hptc_cluster/adm/logs/ovp directory. The file name for log files have the form
verify_nodename_mmddyy;themmddyy portion is a date stamp in month, d ay, year form.
The file named current in that directory is a symbolic link to the m ost recent log file.
See ovp

command and its options.
15.3 Using the dgemm Utility to Analyze Perfo
rmance
Use the dgemm utility to detect an y nodes that may not b e performing at their peak performance.
When a CPU is not performing at its peak effi
ciency, the dgemm util ity displays a WARNING
message.
Be sure to run this command from a system-wide d irectory, such as /hptc_cluster,
because the dgemm utility’s output files are written by the nodes. By default, the dgemm
utility creates two o utput files:
• yyyymmdd.log
• yyyymmdd.chk
The yyyymmdd designates the year, m onth, and day the file was created. If the
detailed-output-flag is set to .true., additional log files for each processor are
created.
_________________________ Note _________________________
Running the dgemm utility subsequently on the same day and from the same
directory overwrites the previous .log and .chk files.
By default, the dgemm u tility iden
tifies nodes CPUs with an average perform ance less than
90% of their peak. The number of CPU
s per node is one, for the purpose of calculating the
average perform ance. You can ove
rride t hese default values by specifying the override values
in an input f ile named input in the
(system-wide) directory from which the dgemm utility
is invoked. The file has the follo
wing form:
